COMBINEDSPRAY AND PINTBRUSH.

Application med apra 1o, 1922. serial No. 551,183.

To all whom t may concern:

Be it known that I, JOHN G. b'oHMiD'r, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented a new and useful Improvement in Combined Sprayand Paintbrushes, of which the following is a full, clear, and exactdescription.

My inventon relates to improvements in combined spray and paint brushes,and it consists in the combinations, constructions,

and arrangements herein described and claimed.

An object of my invention is to provide a combined spray and paint brushwhich has the advantages of the spray and of the ordinary paint brushwithout the disadvantages of either.

A further object of my invention is to provide a device of the characterdescribed in which a plurality of nozzles are used for applying thespray, whereby a more even coat of paint is effected.

A further object of my invention is to provide a device of the characterdescribed in which the spray is adjustable with respect to the paintbrushes.

A further object of my invention is to provide a device of the characterdescribed in which the parts are readily assembled for use o rdisassembled for cleaning.

A further object of my invention is to provide a device of the characterdescribed which is simple in construction, and is dura ble and eicientfor the purpose intended.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended-claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which- Figure 1 is a side elevation of thedevice,

Figure 2 is a plan view of the device, and

Figure 3 is a longitudinal section of the spray.

In carrying out my invention, I provide a spray brush 1 which has aninner paint or other liquid receiving reservoir 2, and an annularcompressed air chamber 3 (see Fig ures 1 and 3). The chamber 3 isdisposed concentrically around the chamber 2 and is provided with aninlet. 4. The chamber lor reservoir 2 is provided with an inlet 5. The

5 chamber 2 has a plurality of outlet openings 6 which are alined withrespect to each other and which are disposed on the opposite side towhich the inlets 4 and 5 are disposed. Nipples 7 of the shape shown inFigure 3 are disposed in the openings 6 and project through threadedopenings 8 in the outer wall of the chamber 3. It is obvious that thereare as many openings 8 as there are openings 6, and that each opening 6carries a nipple 7. The outer wall 9 of the member 1 carries nozzles 10.These nozzles have threaded Shanks 11 which are disposed in the openings8, whereby the nozzles are securely locked -in place. The bore of thenozzles 10 are tapered and receive the ends of the nipples 6. Ifdesired. the bores 12 of the nozzles 10 may be reduced so as to bearagainst the outer end of the nipples 6. In this case, the portion of thenozzle 10 which bears against the nipple 6 would be provided withgrooves through which the compressed air from the chamber 3 is passed.The bore of the nipples 6 is alined with the exit opening 13 of thenozzles 10 so that paint or any other liquid in the container 2 may passthrough the nipples 6 and out through the openings 13.

The outlets 4 and 5 are disposed in an annular projection 14 which isintegral with the member 1. A hollow handle 15 is disposed over theprojection 14 and has its sides 16 extended so as to enclose the sidesof the member 1 (see Figure 1). The handle 15 encloses the pipes 17 and18 which are disposed in the inlet openings 4 and 5. The pipes 17 and 18may be threaded, if desired, so as to rigidly secure the pipes to thepro` jection 14. As clearly shown in Figure 2, the pipes 17 and 18 areconnected to conn duits 19 and 20, these conduits being provided withvalves 21 and 22. The conduit 19 is adapted to convey compressed air tothe chamber 3 and the conduit 2O is adapt* ed to convey paint or a likeliquid to the chamber 2.

A metal saddle 23 is clamped in adjusted position to the handle 15 bymeans of a nut 24. This saddle has laterally extending arms 25 which areprovided with slots 2G therein (see F'igure`2). Paint brushes 2T aresecured to thearms 25 by means of set screws 28. It is obvious from theforegoing structure that the brushes 27 may be moved toward or away fromthe spray brush 1. It is also to be noted that the brushes may be swungangularly with respect to each other.

F rom the foregoing description of the various parts of the device, theoperation thereof may be readily understood. rllhe handle 15 ispreferably adjusted with respect to the frame 23 so that the nozzles 10are spaced away from the endsv oli' the brushes 27. ln Figure l l haveshown a dotted line 29 which represents the wall of an object to whichthe liquid, such as paint or the lilre, is to beapplied. The nozzles l0do not touch the wall 29 and are preferably spaced the distance from thewall whichis shown in Figure l.

lin applying a liquid, such as paint or calcimine, to lthe wall 29, thevalves 2l and- 22 are opened to the required distance so as to permitthe required pressire to be applied to the compressed air and to theliquid. The liquid will How out through the nipples 6 and into theopenings 13 where it will come into engagement with the compressed. air`from the chamber 8. rlihe compressed air will-drivethe liquid outwardlywith-suiiicient force tomake a spray. rl`his spray willcontactsi'viththe wall to whichA the device is applied. lin the useofordinary sprays in 'which paint, varnish, calcimine, or other decorativecoating is to be applied to a wall, a slight air current or a draftcarries the atomized' particles fromy the point of the intendedapplication, somev being entirely carried away and others being droppedon the ground'causinga loss of material and sloppy work.Y With mypresent device, however, the brushes 27 act as a protective shield andalso apply the liquidon the wall in the manner in which the ordinarypaint brush applies thel liquid to a wall. As' the liquid is beingsprayed upon the wall, the device is moved so as to cause either of thebrushes 27 to engage with the liquid on the wall. lt is ob-vious thatthe device may be moved as :tast as desired, since the liquid will besupplied to the brushes at a constant flow. The nozzles l0 are providedin a row so as to give a more uniform flow to the liquid and over agreat area. As heretofore stated, the brushes 27 may be moved toward oraway from the nozzles l0, or may be swung an ularly with respect to eachother. he brushes may be detached and cleaned in the ordinary manner, ornew brushes may be substituted for the old ones. As heretofore stated,the device is very simple in construction, and is eiicient and durablefor the purpose intended. lt has the advantages of the paint brush andthe spray without the disadvantages of either.
